Facilitation of depiction of geographic relationships via a user interface

ABSTRACT

Generation/rendering of a 2D perspective/view of a geographic region, e.g. a map the world or portion thereof, superimposed over which are indicators of related data items and graphical representations of the relationships therebetween is disclosed. Based on location data associated with each data item, a relative geographic presentation within, or otherwise superimposed over, the 2D presentation is generated relative to a 3D representation of the geographic region. Graphical interconnections are then derived based on the positions of the data items relative to each other and depicted in a manner which shows both the relationship between the data items and the geographic relationship with respect to the geographic region. The graphical interconnections may further be derived in a manner so as to depict a or other wise follow the perspective depicted by the 2D view, e.g. as arcs between related data items conforming to the depicted spherical contour of a globe.

BACKGROUND

Internet communications applications such as, for example, e-mail, instant-messaging, telephony (voice over IP, or VoIP), or e-commerce require users to exchange contact information prior to initiating communication between one or more users. Exceptions to this include community-based or topic-oriented applications, such as newsgroups, chat boards, membership websites, or hobby websites, where communication among users may be controlled by the particular application. On the Internet, users who do not know one another, but who may have reason to communicate, may be limited by two main factors: 1) the availability of contact information for those with whom they wish to communicate; and 2) the capabilities of an application (e.g., a website), such as whether the provider permits communication among users utilizing the application. For example, users visiting the same web page may have at least a common interest in the content of that page, yet they normally have no way of discovering this, nor do they have means for communicating with other users. To identify and/or communicate with users having similar interests, a user must know such persons in advance or rely on a facility provided by the application (i.e., the website).

While users may share links or start a conversation through emails, email is not an optimal mechanism for such activities. instead, social networks may change the way users communicate with one another by providing a better mechanism for users to easily share information and engage in a conversation with other users.

A Social Network may refer to a community of members, participants, users or other individuals that share similar values or interests. Each member is typically associated with a personal profile, which may contain demographics, psychographics or professional information relating to the user. Each member may have from zero to many connections or relationships with other members within the social network. Each member may engage in activities, such as email communications, information sharing, etc., with other members. These individuals may grow the social network community by inviting others to join/connect to their community. A social network may also include individuals who engage in some common real-time activities online and share some common context. This includes, but is not limit to, shopping at the same online e-merchant website, browsing the same or related content pages, engaging in an online event or activities at the same time. A social network may extend to activities and individuals engaging in activities around a web page or an object referred to by such a web page. As used herein, the term “users” may include members, guest members, and others accessing a social network, and the term “social” is used in broadest sense to refer to communities of interest.

A social networking service is an electronic or otherwise online/network based service that provides a platform for, or otherwise facilitates, creating and/or building social networks and/or relationships among people who share interests. Social networking services may facility one or more social networks, i.e. non-overlapping groups of interconnected users. A user of a typical social network service may be able to create a profile that lists, for example, information about the user as well as social links (e.g., friends of the user). For example, the user may post ideas, activities, events, interests, and contact information on their user profile. The user may be able to upload pictures to their profile, post blog entries, search for other users, and/or store a list of contacts.

The social networking service may include applications which implement forums, where the user may communicate with other users. The user may be able to create and/or subscribe to groups that share common interests or affiliations, and the user may be able to send or receive comments and other content to or from the other group members. The social networking service may provide controls that allow the user to determine which other users may view the user profile or contact the user, and to which users profile changes or updates are reported or pushed.

Facebook is an example of a widely used social networking service. A Facebook user creates a profile for other users to view. The user may add other users as friends, and these friends may be automatically notified when the user updates his or her profile. For example, the friends of the user may be notified when, for example, the user uploads new pictures or changes his or her status to “at work.” The Facebook user may set one or more parts of the profile to “public” (e.g., all Facebook user may view the one or more parts of the profile), and may set parts of the profile to “private” (e.g., only friends may view the one or more parts of the profile).

Twitter is another example of a widely used social networking service. A Twitter user may send and receive text-based posts of up to 140 characters, known as “tweets.” The user may subscribe to other users' tweets, and other users may subscribe to the user's tweets (e.g., followers). Tweets are public by default, but the user may restrict messages to be private such that only followers of the user may see the tweet. Due to the content limit (e.g., up to 140 characters), tweets may direct followers to content-hosting services such as, for example, Twitpic to accommodate multimedia content and text longer than 140 characters.

Social network services are, generally speaking, content aggregation and distribution systems which aggregate content items continuously supplied by each user, and other sources, into content storage associated with that user, e.g. a profile web page, twitter stream, etc., and redistribute those content items, by selectively allowing access to each user's content storage, to selected overlapping or non-overlapping subsets of other participants based on dynamic and/or static permissions, privacy settings, profile attributes, etc. set by each user which define what content items, or types of content, that user wishes to see of other users and/or what of their own content items or types they wish to allow other selected users to see. The permissions/settings/attributes of all of the users form a matrix of cross-permissions which effectively defines what content items and/or users each user “sees” or is able to discover, e.g. that user's “universe”, when they access the system. The social network system continuously resolves these cross permissions as content items are received so as to properly redistribute, i.e. push and/or respond to requests/queries for access to, those items. As participants connect to the system to receive updates on a an ad hoc basis, content items may be stored up and delivered in batch upon the connection/request of a participant. Content discovery/search must also be facilitated to allow participants to search/discover content items or sources/categories thereof, that the source thereof has suitably permissioned, and modify their permissions so as to obtain prior content items and/or receive distributions of new content from those sources.

The primary feature that is common among most social network services is the user profile. Users typically establish an account with the social networking service by providing a name and other identifying information, and before any action may be taken in connection with the user profile, the user logs in to the account by supplying an account identifier and a password. The profile may include biographic data such as birthday, gender, current location, schools attended, employment experiences, and personal relationships for searching and viewing by other users. Further information that may provide an even more detailed picture of the profile owner and his personality may be added, such as religious affiliation, personal philosophies, tastes in music, literature, cinema, television, athletic teams, and so on.

Links to other users or contacts may be formally established and publicized on a user's profile as well, which may then permit direct communications via e-mail like messages between the user and the contacts. In some systems, real-time chat with concurrently online contacts may also be possible. Access to the profile information may be restricted based upon the level of affiliation to its owner. For example, contacts having a direct “friendship” link to a given user may be able to view the complete profile information thereof, while those having only a secondary affiliation (friend of a friend) may be able to view only the basic biographic information. The establishment of a friendship “network” is understood to facilitate new users to the social network to establish their own direct links to common friends and, thereby, access to the content of those profiles.

Specific user-to-user communications is a significant aspect of most social networking services, but another feature which perhaps eclipses this is the broadcasting of information to everyone within the user's circle of contacts. Specific names and implementations may vary, with some social networking services referring to this feature as a “wall,” while others refer to this feature as “comments,” “tweets,” or others. Regardless of the terminology employed, the feature is essentially the same—a variety of content can be posted by the profile owner or by the profile owner's contacts for viewing by those within the user's network of friends. This content may include text messages, Uniform Resource Locator (IRIS) including links to other webpages, photographs, and videos. With the proliferation of GPS (Global Positioning Satellite)-enabled mobile devices with Internet access capabilities, location coordinate data may also be posted. There may be enhancements to the display of the foregoing data, such as showing the location on a map overlaid on the rendered page, or a preview of the webpage for a link.

Unfortunately, users with varying interests often have a difficult time locating each other within such social networking systems as it necessitates first identifying and establishing a link with another user or a social network of users to which they belong, which may require “knowing” another user who “knows” of a user of interest and/or reliance upon the ability to search and discover information made public by a user which identifies their interests, if any. Additionally, many steps and a significant amount of time may be required prior to commencing the actual interaction, e.g. that user may have to “accept” a request to be connected.

Creating communities of people with similar interests may also suffer drawbacks and difficulties. It may be time consuming and difficult to create a community of interest for users that permits interaction. Communities of interest may be difficult to create, especially for neophyte computer users with little experience in the field. If separate software, applets, or plugins are needed to access the community, it may be difficult to convince prospective community members to find a copy of or go to the website location for downloading the necessary software, download the software, install and configure it, and use the software to communicate with the community. Additionally, it may be difficult to publicize the existence of such a community to others.

Generally, in existing social networking services, the user profile based access permission premise may make it difficult for users to discover and expand their interconnections with other users having similar interests.

DETAILED DESCRIPTION

The disclosed embodiments relate to facilitation of discovery of content of interest and users with shared interests by enabling appreciation for a user's geographical, geo-physical and/or geo-political relationship with other users and reducing linguistic impediments to the ability of a user to comprehend content provided by other users. As opposed to identifying just topical interests in common with another user, the disclosed embodiments enable further discovery of content of interest and/or users with common interests based on geographic and/or cultural relationships and, by providing language translation, as will be described, enable exchange of content items among user who speak different languages.

In particular, the disclosed embodiments relate to the generation and rendering of a two dimensional perspective or other view of one or more geographic regions, such as a map the world or a portion thereof, superimposed over which are indicators of related data items, as described herein, and graphical representations of the relationships there between. In one embodiment, based on location data associated with each of the data items, a relative geographic presentation within or otherwise superimposed over the two dimensional presentation is generated relative to a three dimensional representation of the geographic region, e.g. a globe. Graphical interconnections are then derived based on the positions of the data items relative to each other and depicted in a manner which shows both the relationship between the data items and the geographic relationship with respect to the geographic region. The graphical interconnections may further be derived in a manner so as to depict or otherwise follow the perspective depicted by the two dimensional view, e.g. where the two dimensional view shows a portion of the geographic region as a portion of a sphere, the graphical interconnections may be computed as arcs or curved lines extending between the related data items, where the arc conforms to the depicted spherical contour, e.g. the curvature of the globe. With respect to two dimensional depictions of a three dimensional region, e.g. a globe, where related items are geographically located, and therefore depicted, on opposite sides of a depicted “horizon”, the graphical interconnection is derived and depicted as extending to the boundary of the two dimensional depiction so as to present the appearance of extending from the origin data item “over the horizon” to, i.e. in the direction of, the related data item. As the user modifies the view, e.g. spins the globe, via interaction with the user interface, such as by touching, dragging, etc., the above process is repeated to redraw the positions of the data items and the connections there between. For example, as a particular data item, which was initially out of view “over the horizon” is brought into view as the view is modified, the connection therewith is redrawn to show its connection with the origin data item. As this refresh/redrawing may occur quickly, e.g. at 30 frames per second, the user's perception may be of being able to seamlessly follow connections and relationships between a selected origin data item and the related data items connected therewith.

The disclosed embodiments may be used in conjunction with systems and methods for efficiently and automatically distributing content among a plurality of users which may be used to implement a social networking service. Content items, which may include “posts” submitted by one user, e.g. responsive to a “post” submitted by another user, are stored in association with data indicative of a specified subset of an interest category classifications defined by the system. Users of the system further specify a subset of the interest category classifications to define their interests. The system then provides content items of interest to the user by mapping, as will be described, the defined interests of the user against the interests associated with the stored content items. The disclosed embodiments enable users to discover and expand their interconnections with other users which may have similar interests.

In particular, content distribution systems, which may be used with the disclosed embodiments, may effectively continuously evaluate a user's defined interests against a database of previously received content items and their associated interest classifications to identify an intersection thereof and enable effectively continuous and/or automated discovery of content items of interest, and interconnection with users responsible therefore which, by virtue of their submission of such content, are likely to share one or more common interests. Furthermore, discovery of content items of interest may be enhanced via a search mechanism/engine which evaluates a search query to return search results from a content database and further iteratively broadens the scope of the search parameters, autonomously or according to user specified preferences, to retrieve additional relevant search results which, scope-wise, surround the initial results if any. In this way, a narrow search which may, by itself produce few if any results, will still provide some results to the user and/or attempt to flush out and return a defined/threshold number of search results to user.

Herein, the phrase “coupled with” is defined to mean directly connected to or indirectly connected through one or more intermediate components. Such intermediate components may include both hardware and software based components. Further, to clarify the use in the pending claims and to hereby provide notice to the public, the phrases “at least one of <A>, <B>, . . . and <N>” or “at least one of <A>, <b>, . . . <N>, or combinations thereof” are defined by the Applicant in the broadest sense, superseding any other implied definitions herebefore or hereinafter unless expressly asserted by the Applicant to the contrary, to mean one or more elements selected from the group comprising A, B, . . . and N, that is to say, any combination of one or more of the elements A, B, . . . or N including any one element alone or in combination with one or more of the other elements which may also include, in combination, additional elements not listed.

FIG. 1 depicts a block diagram of an example transaction processing system 100 for distributing content responsive to transaction requests therefore and which may be referred to as a content distribution system 100, which may be used in conjunction with the disclosed embodiments, which, in an exemplary implementation, is implemented as part of a social networking service described above. The example transaction processing system 100 as well as the disclosed embodiments used in conjunction therewith are preferably implemented with computer devices and computer networks, such as those described with respect FIG. 4 and improved as described herein, that allow users, e.g. members or participants, to interact with the social networking service, e.g. submit content items to the social networking service and receive content items submitted by others. It will be appreciated that the plurality of entities utilizing the disclosed embodiments may be referred to by other nomenclature reflecting the role that the particular entity is performing with respect to the disclosed embodiments and that a given entity may perform more than one role depending upon the implementation and the nature of the particular transaction being undertaken, as well as the entity's contractual and/or legal relationship with another participant and/or the system 100.

In particular, FIG. 1 depicts a block diagram of a system 100, which may also be referred to as an architecture, for automated electronic distribution of a content item, provided by an external or internal source, e.g. a client 116 or content generator 134, to the content distribution system 100, to a subset of a plurality of users, e.g. clients 116, such as via a network 138, the content distribution system comprising a processor, 102, memory 104 coupled with the processor and a data store 124 coupled with the processor 102 and/or memory 104, the memory 104 comprising a cache 118 and the data store comprising one or more databases 126, 128, 144 including content database 126. In one embodiment, the network 138, processor 102, memory 104 and data store 124 may be implemented by one or more of the network 420, processor 402, the memory 404 and drive unit 406 described below with respect to FIG. 4. Alternatively, the cache 118 may be stored in the data store 124, or in a separate memory 104 or data store 124 from where the other components of the system 100, as described below, are stored. It will appreciated that the data store 124 could comprise a memory 404 or memory 404 in combination with a drive unit 406 and may be logically and/or physically combined with the memory 104. It will further be appreciated that some data may also be stored in the client device 116. For example, repetitively used data and/or images or other large content may be stored in a local cache memory (not shown) within the device 116 which may be maintained by the system 100. When content is transmitted to the device 116, described herein, references to the locally stored data may be included in transmitted content rather than the data itself thereby conserving communication bandwidth and/or improving latency as between the system 100 and device 116. If the data is not already stored in the device's 116 local cache, e.g. because it was previously referenced or otherwise pre-cached, or the data stored in the local cache is outdated or expired or has otherwise been modified at the system 100, the data may be transmitted or re-transmitted by the system 100 to the device 116. In one embodiment, the system 100 may employ speculative or predictive caching whereby the system 100 attempts to anticipate what content items may be requested by the device 116 in the future, such as based on prior update or search requests, or identified trending content, as described herein, and transmit those content items in advance of an explicit request therefore in order to improve or at least provide the user with the appearance of improved latency/performance/responsiveness. In one embodiment, speculative or predictive caching may only be invoked if elected by the user and/or if the available bandwidth between the system 100 and device 116 exceeds a threshold.

In one embodiment, the cache 118 holds about 100MB of data but it will be appreciated that the size of the cache 118 may be implementation dependent. In one embodiment, the cache 118 is implemented using the REDIS data structure server, sponsored by Redis Labs, located in Mountain View, Calif. The organization and operation of the cache 118 is described in more detail below. In one embodiment, the content database 126, or database 126, stored in the data store 124, comprises a structured database including defined data fields and business logic, such as a SQL database. The operation and organization of the database 126 is further described below

As used herein, a “content item” may refer to a data item or data structure which includes content or links/references thereto, e.g. data such as one or more text strings, images, etc., generated by the system, e.g. via the content generator 134, and/or by a user of the system, such as a “post”, comment, statement, picture, URL/web link, hashtag, etc. A content item may comprise any edit/update to content previously stored in the system 100 or new content submitted thereto. The content may be generated responsive to the content of another content item, such as a response in a conversation, comment on a topic, etc. Thereby, the content item may be related to other content items e.g. via a context, understood by the submitting user. Content items may be characterized as being of a particular content type, which in one embodiment, the available content types include “user”, “conversation”, and “community”. It will be appreciated that the available content types and their attributes are implementation dependent and fewer or more content types may be implemented. Content items may further be associated with, or otherwise include, a subset of one or more interest classifications or categories as will be described below. As will be further described below, a content item may be characterized by or implemented in at least two different formats, one for storage in the database 126 and one for communication to a user, which, as will be described, is also used to store the content item in the cache 118. Furthermore, the content of a content item may be characterized by human communication language, e.g. English, French, Spanish, etc. which may be derived by the system 100 from the content or the content item may further include data indicative thereof to identify the language to the system 100.

In one embodiment, content types define how the content item is stored in the database 126, e.g. the database model/structure, schema/field/table definitions and associated business logic and methods, and content items of different content types may be stored in different manner accordingly. The business logic/methods may be configured to act on and/or be triggered to act by particular content items being stored in the database, e.g. to trigger notifications as will be described below.

Content characterized as being of content type “user” relates to or otherwise describes users/participants of the system 100, i.e. people who have created an account with the system 100, are active in the system 100, have a presence, have a profile page, create posts, and are able to interact with others via the system 100. It will be appreciated that users of the system 100 may include actual persons or entities such as corporations or groups, such as a sports team or club, e.g. where the activities of the user within the system 100 are administrated by a representative thereof. User “content type” content items may include public or private profile data about a user, data identifying and/or linking to other users that are “following” the user, i.e. are interested in receiving notifications relating to the activities of the user in the system 100, or who the user is following, data identifying or linking to the user's activities in the system 100, e.g. content posts to conversations or subscribed communities, and/or data identifying or linking to the user's preferences, privacy settings, e.g. defining who can contact or follow the user, roles within the system, e.g. administrator, moderator, etc. For example, user content items may include the user's name, biographical information, geographic location or address, username, image to use for presentation of posts via the user interface, profile image, and current authentication token (described in more detail below). User “content type” content items may further include a selected subset of interest classifications, i.e. keywords, as will be described below. User “content type” content items may further include analytics data which tracks the user's behavior in interacting with the system 100. For example, in one embodiment, the system 100 may implement game mechanics, i.e. rules, methods or logic, wherein User “content type” content items may include an accumulation of points “earned” by the user or an adjustable weight or score value, determined via, for example, based on the user's interactions with the system 100, such as by posting content items, etc. and which may represent the “influence” of a particular user. Determining on-line influence of a user in social media may be of use, such as to marketers and public relation (PR) professionals, to determine, filter or otherwise identify relevant subsets of users who should be listened to or otherwise engaged. As used herein, a user profile may refer to the collection of content items of content type “user” stored in the system all relating to a particular user. A user profile database may refer to the collection of user profiles. In one implementation, a separate user profile database may be provided to store particular user information such as login/authentication credentials, authentication tokens, specific user data, such as data intended to be kept private, etc.

Content items of content type “conversation” include posts, responses, messages or other interactions with other users, by users, generally in a two or more way exchange initiated by one user to at least one other user, either directly or implicitly, e.g. via a relationship of the content item to a common interest between the users, as will be described. Users participating in conversations may be referred to as participants. A conversation may be characterized by a context, e.g. a subject or associated set of interest classifications and a content item of content type “conversation” may include data indicative thereof. In one embodiment, content items of a conversation may be accessible only to participants thereof or the accessibility to non-participating users may be selectively controlled. Alternatively, any user may be able to access such content items, i.e. “listen” in on the conversation.

Content items of content type “community” include multiple different conversations which all relate to a common context/topic/interest classification and, like conversations, includes posts, responses, messages or other interactions with other users, by users, generally in a two or more way exchange initiated by one user to at least one other user, either directly or implicitly, e.g. via a relationship of the content item to a common interest between the users, as will be described. Users participating in community may be referred to as subscribers. A community may be characterized by a context wherein each conversation within the community may be further characterized by a sub-context, e.g. a subject or associated set of interest classifications and a content item of content type “community” may include data indicative thereof. in one embodiment, content items of a community may be accessible only to subscribers thereof or the accessibility to non-subscribing users may be selectively controlled, such as via invitations. Alternatively, any user may be able to access such content items, i.e. “listen” in on the community. Conceptually, a community may act more like a forum directed to a particular topic with multiple conversations occurring related to various sub-topics. Alternatively, it will be appreciated that conversation content items may be implemented to allow multiple contexts to be associated where conversation content items having an associated context in common are considered part of the same community. Community content items may further be associated with data, e.g. a separate data structure, defining the context of the community, the subscribing users, assigning a particular user as a moderator of the community and defining which users of the system 100 may subscribe and/or submit posts to the community, and/or identifying a sponsoring entity or user, e.g. allowing for a branded presentation of the community to users.

In one embodiment, if two or more users are subscribed to the same community or participating in the same conversation and are determined to be contemporaneously actively connected with the system 100, such as by detecting an active “live” socket indicating a current connection thereof, any posts or updates to that conversation or community may be immediately distributed to the other actively connected subscribers/participants, such as via the live push module 140 which will described in more detail below.

As will be described, the system 100 generally manages the storage and retrieval of content items based on content type and content items are stored in an arrangement, logical and/or physical, based thereon, referred to as “containers”, “interest containers”, “silos”, “buckets”, etc., so as to store related content items, e.g. content items of the same content type and having the same interest classifications, together. In one embodiment there may be around 1300 different containers however it will be appreciated that the number of containers is implementation dependent and may depend on both the resources, e.g. memory and processing capacity, of the system 100 as well as the desired level of granularity by which the content items are to be organized and/or made discoverable. It will be appreciated that the container based arrangement for storing content items may be implemented by physically storing content items belonging to the same container in the same area of the cache 118 or database 126 and/or via a logical linking of disparately stored content items, e.g. using address or reference pointers, to logically group content items of the same container. As used herein, an interest container refers to a collection of related content items, which may be related by one or more keywords or keyword sets, as described elsewhere herein, which are stored logically and/or physically together and which the system 100 may access, explicitly or by reference, as a collection. As shown in FIG. 2, the content database 126 may include containers for user content items 222, conversation content items 224 and community content items 226. It will be appreciated that in different implementations thereby may be different or additional containers within database 126. The cache 118 may similarly be organized by containers as described. Each of the containers 222, 224, 226 of the database 126 may be further subdivided into sub-containers, which herein may simply be referred to as containers, based on the associated interest categories of the content items stored therein. As will be described, the container arrangement facilitates rapid retrieval of related content items, or subsets thereof, based on the relevant keywords/interest categories.

Other functionality and associated content/data types and data structures may also be supported. For example, direct messaging may be provided which allows one user to directly send a message to another user, such as by interacting with a messaging interface provided on the receiving users profile/application screen. Direct messages may be private and without a context. Direct messages may be stored in the data store 124 using data structures referred to as “dialogs.” Language translation, as will be described in more detail below, may be provided. A user may define privacy settings within the system 100, e.g. via their user profile, which are factored into the business logic to control which other users may be permitted to send them direct messages.

Notification messages may be provided which indicate to a user that a particular event has occurred in the system 100. Notifications may be triggered by business logic within the database 126 or elsewhere in the system 100 based activities of users or the system 100 itself, system 100 generated content items. For example, new content items or updates or modifications to previously submitted content items may trigger notification messages to be communicated to followers of a user submitting or updating the content item, and/or participating or subscribed users to updated conversations or communities. Notification messages may be presented to users via the user interface 146 of their device 116. Notification messages may be stored in a data structure in conjunction with data indicative of the life cycle of that message, e.g. whether it was sent, received, read, deleted, etc. A user may define privacy settings, e.g. via their user profile, which are factored into the business logic, to control the receipt of notification messages and/or the generation of notification messages based on their activities.

A user role data model/structure may be provided and stored in the data store 124 which is associated with all communities and stores a list of communities to which each user is subscribed and the roles they have within those communities, e.g. owner, moderator, contributor, read only, etc.

As described above, content items may be generated by users and submitted to the system 100 or they may be created by the system 100 itself. User originated content items may include posts, comments, images or other user generated content, URL web links, hashtags, content copied from other web pages/sites, etc. In one embodiment, the interface 146 used by the user via their client device 116 may permit them to navigate to any web page or web site and “capture” content therefrom as a content item to be submitted to the system 100. Alternatively, the system 100 may provide a widget, overlay or web browser plug-in or app which provides this functionality. For example, the interface may provide a “like” or “post” button, implemented for example via a web browser plugin application, which appears on the user's display as they navigate to web sites and web pages. When the user selects the like button proximate to web content they wish to submit to the system 100, a link is generated or the content is extracted, e.g. by the content scraping processing module 220 (shown in FIG. 2) of the content generator 134, formed into a content item and transmitted to the system 100. In one implementation, a Ruby on Rails GEM known as MetaInspector is utilized to extract the web content and form the content item. In one embodiment used in conjunction with the iOS operating system published by Apple, Inc., located in Cupertino, Calif., the interface or app may be integrated with web browser provided by the operating system, referred to as deep linking, which allows a user to select a link, such as via long-press or 3D press interface interaction, an elect to have the link or data related thereto be transferred by the operating system to the interface or app. Further, the system 100 may generate content items, which may be referred to as “stories”, using, e.g. the content generator 134 and trending processing module 218 (shown in FIG. 2) thereof, which accesses defined external content sources, such as web sites or news feed services which provide, for example, current news or entertainment stories, extracts, using, for example the content scraping processing module 220, content therefrom and forms the extracted content into content items, and associates appropriate interest classifications therewith, which are then associated with/added to relevant conversations or communities. System 100 generated content may be used to fill content gaps when there is little user activity, to seed communities or conversations to initiate user interaction therewith, or generally to provide content of interest related to current trends or events to users.

As was described above, content items are associated with one or more interest classifications, also referred to as interest categories or classifications, which define the context of the content of the content item for the purpose of distributing and/or facilitating discovery of that content item as described herein. Furthermore, users of the system 100 specify one or more interest classifications to define what their interests are. The system 100 maps or otherwise correlates the interests of each user against the interest classification(s) of content items to determine which content items to transmit to a user.

In one embodiment, these interest classifications/categories are implemented as keyword metadata, keywords or tags associated with the content items, e.g. stored in conjunction with the content items, either explicitly or by reference as will be described. Generally, tags may be considered a “bottom-up” type of classification, compared to hierarchies, which are “top-down”. In a traditional hierarchical system (taxonomy), the designer sets out a limited number of terms to use for classification, and there is one correct way to classify each item. In a tagging system, there are an unlimited number of ways to classify an item, and there is no “wrong” choice. Instead of belonging to one category, an item may have several different tags. Some researchers and applications have experimented with combining structured hierarchy and “flat” tagging to aid in information retrieval. Tags may describe or define some aspect of an information resource (such as a document, digital image, relational table, or web page) and may capture knowledge in the form of descriptions, categorizations, classifications, semantics, comments, notes, annotations, hyperdata, hyperlinks, or references and may be collected in tag profiles which reference an information resource that resides in a distributed, and often heterogeneous, storage repository. Tags may be used to capture insights, expertise, attributes, dependencies, or relationships associated with a data resource.

As was described above, content items contain content generated by users or by the system 100 however, the semantics, meaning or context of that content, while being potentially easy, subject to any ambiguity therein, for a human being to comprehend, may not be readily discerned by the system 100, particularly when content is provided in different languages, to enable categorization or interest/context based search functions. Further, interests, or the semantics thereof, of a user may be difficult to formulate and document in a manner which can be readily electronically processed. Generally, the meaning or relevance of content or the interests of users reside in the knowledge of the user/creator. Knowledge may be defined as information possessed in the mind of an individual: it is personalized or subjective information related to facts, procedures, concepts, interpretations, ideas, observations and judgments (which may or may not be unique, useful, accurate, or structurable). Tags facilitate the capture of knowledge in the system 100, e.g. of the meaning/relevance of content or the interest of users.

In one embodiment, a taxonomy of tags, e.g. keyword metadata or keywords, is provided. Alternatively, the system 100 may permit users to define or curate the available keywords, e.g. a folksonorny, or a combination of a taxonomy and folksonomy may be implemented. In one embodiment, the available keyword metadata of the system 100 is organized into a plurality of keyword sets/hierarchies, where each keyword set includes a hierarchical sequence of keywords, wherein for each keyword set a first keyword of the sequence of keywords defines semantics or a context, different from the semantics or context defined by a first keyword of a different keyword set, and each subsequent keyword of the sequence of the keyword set defines a narrowing of the semantics/context over the previous keyword of the sequence of the keyword set. For example, one keyword set may include the sequence of keywords: Drinks; Alcohol; Wine; White; Pino Grigio; California; Berringer. Another keyword set may include the sequence of keywords: World: North America: United States: Illinois: Cook County: Chicago: Lincoln Park. It will be appreciated that the narrowing of the semantics/context may be explicit based on the definition/semantics of the keyword itself and/or implicit based the ordering of the keywords in the sequence within the keyword set, i.e. the first keyword of a keyword set is always the broadest followed by the next narrowest keyword and so on regardless of the semantics/context associated with the keyword itself. Keyword sets are defined for various classifications of interests, and various scopes thereof, The number of keyword sets, as well as the number keywords/levels within each set is implementation dependent and, theoretically, unlimited, In one embodiment, each keyword set includes up to three keywords but may include more or less. In one embodiment, keyword sets may intersect, i.e. have one or more of the same keywords in common, but the appearance of those keywords in each keyword set sequence may vary. In an alternate embodiment, keywords sets do not overlap, i.e. each keyword is included in only one keyword set.

Content items are associated with data indicative of a subset of one or more of the keywords selected from the plurality of key word sets. It will be understood that, as used herein, a subset of a set may refer to the entire set, e.g. an “improper” subset. Any of the keywords in a keyword set may be selected based on its breadth, applicability, etc. Selection of any keyword in a set may automatically associate all broader keywords of the set, just the next broadest, or just the overall broadest keyword thereof, with the content item, keywords from multiple keywords sets may be selected. The associated keywords for a given content item may be specified by the submitting user, may be defined or otherwise inherited based on the context of the submission, e.g. a response to post in a conversation may inherit associated keywords of that post, automatically defined by the system 100 based on other attributes of the content item or the by which it was obtained, or combinations thereof.

Users are also associated with a subset of one or more of the keywords selected form the plurality of keyword sets wherein the keywords are selected, explicitly or implicitly by user and/or system 100, based on their interests. Any of the keywords in a keyword set may be selected based on its breadth, applicability, etc. keywords from multiple keywords sets may be selected. Keywords may be selected by the user and/or assigned automatically by the system 100, either via explicit action or derived/implied from actions by the user, such as based user activity within the system 100, e.g. if a user selects a community to view the content thereof, the associated keywords of that community may be assigned to the user. in one embodiment, user selected keywords are stored separate, e.g. in a separate content item or container associated with that user, from keywords which are automatically selected by the system 100 for that user.

Keywords, for association with a user or with a content item, may be selected from a user interface (not shown) provided by the system 100 via the client 116/UI 146, such as a hierarchical selection interface which allows a user to navigate the various keyword sets and pick from the available keywords therein. In one embodiment, this interface may be presented as a circle or wheel along the circumference of which are selectable indicators of the available keyword sets. Selecting an indicator, or hovering a pointer there over, expands the keyword set, in its entirety or incrementally (not shown), to display the sequence of keywords therein available for selection. Alternatively, the interface could comprise a hierarchical menu tree featuring selectable and/or expandable menus and sub-menus of keywords. In one embodiment, selection of a particular keyword for association with the user or with a content item selects the selected keyword and all broader keywords in the sequence. It will be appreciated that the more keywords sets are associated with a user or content item, the broader the applicable content/interests may be defined where as the more keywords within each set which are associated with the content item or user, the narrower the applicable content/interest may be defined.

Similarly, a user interface may be provided by the system 100, such as via the client 116/UI 146, which enables a user to visualize the selected keywords associated with the user or with the content item. in one embodiment, this visualization may take the form of a hierarchical or tree display showing each keyword and the keyword set to which it belongs. Where keyword sets are permitted to overlap, intersections among selected keywords may be depicted. In one embodiment, the tree visualization is arranged in a circular/branching pattern to resemble a snow-flake, lattice, organizational chart, outline, etc.

In one embodiment, the keyword sets are stored in an interest database or data structure stored in the data store 124 wherein each keyword is associated with a unique identifier. Associations between users or content items and keywords are implemented by storing the associated identifiers of the selected keywords in association therewith. Alternatively, the actual selected keywords may be stored in association with the content item or user. In another alternative embodiment, identifiers of the users or content items may be stored in association with the selected keywords. In one embodiment, keywords of different spoken languages which have the same meaning may be stored together in association with same keyword identifier, thereby facilitating multilingual support. Alternatively, given the cultural and contextual differences among keywords of different languages, even where keywords of different languages are generally accepted as having the same meaning, all such keywords may be treated separately. In one embodiment, each keyword may be further associated with a language code, e.g., selected from table below, indicating the particular language of the keyword to distinguish those keywords which have the same spelling or appearance in multiple languages.

As was describe above, and explained in more detail below, content items are stored in the database 126 or cache 118 in containers, e.g. containers 222, 224, 226 shown in FIG. 2, which are defined based on the associated keyword data. In this manner, thereby, received content items are stored in association with other stored previously received content items whose associated data is indicative of a subset of the plurality of keywords which at least partially overlaps the subset of the plurality of keywords associated with the received content item, e.g. within the same conversation and/or container.

Generally, the association of keywords facilitates the discovery of content that is of interest to the user by enabling the system 100 to correlate the interests of the user against the context/relevance of the available content items and content items related thereto. In one implementation this may be accomplished by mapping the keywords associated with a content item on to the keywords associated with the user in a similar manner to they way a fingerprint is matched. Inexact matches may be allowed and/or the degree and manner in which associated subsets of keywords are required to overlap and/or allowed to diverge and still be considered a match may vary. in one embodiment, the system 100 employs fuzzy logic, a form of many-valued logic, to determine, based on associated keywords/keyword sets, which content items match the given interests of a user. In one embodiment, the user may specify, as will be described below, the degree to which the keywords/keyword sets defining their interest categories must match the keywords/keyword sets associated with content items and/or the degree to which particular subsets of keywords/keyword sets defining their interests or associated with a given content item must match. In one implementation, the user interface 146 displays a slide control which defines a range of exactness for the system 100 when identifying suitable content items for the user, which allows a user to set, via moving an indicator along the slide control, the desired exactness from less specific/exact to specific/exact. Storing content items in containers based on their associated keywords facilitate rapid retrieval of those content items, and content items related thereto, responsive to a request, e.g. a search request, therefore.

Once a user has identified content items of interest, e.g. a conversation, community or other user, they may choose to participate in the conversation, subscribe to the community and/or follow the user. As was described above, in one embodiment, separate data structures are maintained by the system 100 to track each user's participation in conversations, subscriptions to communities or followed users so that new content items and updates associated therewith may be provided to the user. Accordingly, if a user subsequently alters their associated keywords, e.g. modifies their interests/interest profile, their current participation, subscriptions or follows will not change, unless explicitly modified by the user. In an alternative embodiment, if a user modifies their keywords, i.e. changes their interest profile, such that a particular conversation they are participating in, community they are subscribed to or user they are following would not have been provided to them via a search based on their current interest profile, they will be removed from those conversations, un subscribed from those communities or unfollowed from those users, either automatically or upon receipt of a confirmation from the user.

As was described above, the content distribution system 100 may be implemented with one or more mainframe, desktop or other computers, such as the computer 400 described below with respect to FIG. 4, or clusters thereof, which may be referred to as a “cloud computing system”, “cloud computing environment” or “the cloud,” coupled with a network 138, which may be the network 420 described with respect to FIG. 4. The network environment 138 shown in FIG. 1 in which the content distribution system may be implemented may include exemplary computer/client devices 116 and may include different exemplary methods or media by which a computer/client device 116 may be coupled with the content distribution system 100 or by which a user/participant may communicate, e.g. send and receive, electronically, requests for content items and responses thereto. It will be appreciated that the types of computer/client devices 116 deployed by participants/users and the methods and media by which they communicate with the content distribution system 100 is implementation dependent and may vary and that not all of the depicted computer devices and/or means/media of communication may be used and that other computer devices and/or means/media of communications, now available or later developed may be used, As used herein, a reference to a “user” of the system may refer either or both a human being or a client device 116 operated thereby.

Each computer/client device 116, of which there may be many and each of which may comprise a computer 400 described in more detail below with respect to FIG. 4, may include a central processor that controls the overall operation of the device and a system bus that connects the central processor to ne or more conventional components, such as a network card or modem. Each computer/client device 116 may also include a variety of interface units and drives for reading and writing data or files and communicating with other computer devices and with the content distribution system 100. Depending on the type of computer/client device 116, a user can interact with the device 116 via a user interface/display 146 which may include a keyboard, pointing device, microphone, touch screen, pen device, graphic display or other input or output device now available or later developed. The client device 116 may execute an application which facilitates access to/interaction with the system 100, such as a dedicated or proprietary “app” program specifically designed to facilitate access to/interaction with the system 100 and/or a generic application, such as a web browser application, which facilitates access to/interaction with an application, e.g. web page or web site, available over the network 138 and which may be provided by the system 100, such as via a web server, not shown, which is specifically configured to enable access to/interaction with the system 100 as described herein. References herein to a client or client device 116 will refer to a device 116 which is executing an application or other software, including a web browser application, to provide, or provide access to, an interface specifically configured to facilitate user interaction with the system 100.

An exemplary computer/client device 116 is shown directly connected to system 100, such as via a T1 line, a common local area network (LAN), wide are network (WAN) or other wired and/or wireless medium 138 for connecting computer devices, such as the network 420 shown in FIG. 4 and described below with respect thereto, and may be composed of one or more public, e.g. the Internet, or private wired and/or wireless networks and configured in one or more of the well-known LAN topologies, e.g. star, daisy chain, etc., and may use a variety of different protocols, such as Ethernet, TCP/IP, etc. The exemplary computer devices 116 may communicate with each other and with other computer and other devices which are coupled with the network 138. Computer and other devices may be coupled with the LAN 124 via twisted pair wires, coaxial cable, fiber optics or other wired or wireless media, e.g. WiFi, Bluetooth and/or a cellular telephone based data communications protocol. The exemplary computer/client device 116 may include a laptop or desktop computer, tablet devices, cellular telephone, smart phone, or other wireless proprietary and/or non-proprietary device. It will be appreciated where the network 138 between the client devices 116 and the system 100 utilize multipath protocols such as mesh networking, packet switching, TCP/IP, etc., multiple physical and/or logical communications routes may be available over which a given electronic data transaction request message may travel when being communicated over these networks. The choice of route over all or a portion of the network 138 may or may not be under the control user, the client device 116 and/or the system 100, e.g., routing may be subject to error correction protocols, congestion control protocols, quality of service protocols, outages or intermittent errors.

The operations of client devices 116 shown in FIG. 1 may be controlled by computer-executable instructions stored on a non-transitory computer-readable medium. For example, the exemplary computer device 116 may include computer-executable instructions for receiving content or queries from a user, transmitting that content or query to the system 100 and receiving and presenting responses thereto to the user.

Of course, numerous additional servers, computers, handheld devices, personal digital assistants, telephones and other devices may also be connected to the system 100. Moreover, one skilled in the art will appreciate that the topology shown in FIG. 1 is merely an example and that the components shown in FIG. 1 may include other components not shown and be connected by numerous alternative topologies.

While the content distribution system 100 will be described with reference to the treatment of the submission of single content item or receipt of s single request for previously received content items, in operation it will be appreciated that the disclosed system is continuously/regularly receiving content item submissions or updates and servicing requests for content items. The disclosed databases may be updated in real time, i.e. as content items, or updates, are received and may respond to requests for content in real time. As users may connect and disconnect from the system at will or otherwise on an ad hoc basis, the system 100 is designed to respond to requests for content items in a manner which accounts for a user not being connected to the system 100 at the time a particular content item was received, as will be described.

Referring to FIG. 1, the system 100 further includes a content receiver 106 coupled with the network 138, which may be implemented as a separate component or as one or more logic components, such as on an FPGA which may include a memory or reconfigurable component to store logic and processing component to execute the stored logic, or as first logic 106, e.g. computer program logic, stored in a memory 104, or other non-transitory computer readable medium, and executable by a processor 102, such as the processor 402 and memory 404 described below with respect to FIG. 4, to cause the processor 202 to, or otherwise be operative to receive the content item from the source, e.g. a user device 116 or internally generated by the system 100, the content item being associated, upon receipt or via data included therewith, with data indicative of a subset of a plurality of keywords selected from a plurality of keyword sets, each keyword set comprising a hierarchical sequence of keywords, wherein for each keyword set a first keyword of the sequence of keywords defines a context, different from a context defined by a first keyword of a different keyword set, and each subsequent keyword of the sequence of the keyword set defines a narrowing of the context over the previous keyword of the sequence of the keyword set. Content items may be submitted responsive to request or prompt generated by the system 100 and transmitted to the source or may be unsolicited.

In one embodiment, as was described above, the content distribution system further comprises a category database 148, which may be stored in the data store 124 or memory 104, operative to store the plurality of keyword sets wherein each keyword within each keyword set is identified by a unique identifier, and further wherein the data indicative of a subset of the plurality of keywords comprises the unique identifiers of the respective keywords as stored in the category database 148.

It will be appreciated that the associated subset of keywords for a received content item may be defined by the user prior to submission of the content item and included therewith, or defined by the user after the content item has been submitted, such as via a user interface which presents the content item and provides a mechanism for navigating and selecting one or more keywords from the available keyword sets as was described above. Alternatively, or in addition thereto, the system 100 may automatically assign one or more keywords to the content item upon receipt, such as by analyzing the content of the content item or the context from which the content item was received, e.g, based on attributes of a web page from which the content item was obtained. In one embodiment, when a content item received by the system 100 is related to another content item that was previously received by the system 100, e.g. a response to another post, the newly received content item inherits one or more of the keywords associated with the previously received content item. The subset of keywords associated with a particular content item may be static, i.e. once defined never change, or dynamic, i.e. are modifiable by users or by the system 100 to add and/or remove keywords. Modifications may be restricted by user, e.g. restricted to selected users such as only the submitting user, and/or by type, e.g. keywords may only be added to the subset but not removed.

Where content items or, as will be described below, requests for content items are submitted by users, users may first be required to authenticate or otherwise login to the system 100. An authentication processor 142 may be provided to authenticate or otherwise allow a user to login to the system. The authentication processor 142 may be coupled with a user database (not shown) which maintains data regarding users who are authorized to access the system 100, such as users who have previously registered with the system 100, In implementations of the system 100 where users utilize a client application executing in their device 116 to access the system 100, the client application may implement a login or authentication process with the user to capture the user's login credentials, e.g. user identifier and password. In implementations using a web site or web page to access the system 100, the system 100 may provide functionality which facilitates login/a.uthentication to the system 100. Various methods of login/authentication may be supported including Open Standard for Authorization (“OAuth”), an authorization protocol that allows a third-party website or application to access a user's data without the user needing to share login credentials, via a user's Facebook or Twitter accounts, and using email credentials through an account set up directly with the system 100. Once authenticated with the system 100, the system 100 may provide an authentication token to the user/device 116 which is also stored in the user profile data in the database 126, or elsewhere. The authentication token is then communicated with each transmission to the system 100 by the device 116, e.g. in the user-agent header string. Upon receipt the authentication token is validated against the stored authentication token to confirm that the submission/request is authorized.

The system 100 further includes a database manager 108 coupled with database 126 and the content receiver 106, which may be implemented as a separate component or as one or more logic components, such as on an FPGA which may include a memory or reconfigurable component to store logic and processing component to execute the stored logic, or as second logic 108, e.g. computer program logic, stored in a memory 104, or other non-transitory computer readable medium, and executable by a processor 102, such as the processor 402 and memory 404 described below with respect to FIG. 4, to cause the processor 202 to, or otherwise be operative to store each of the received content item in a first format in the database 126 in association with data indicative of at least a subset of the subset of the plurality of keywords associated with the received content item. This process may be referred to as Content Processing and implemented by a content processing module 216 (shown in FIG. 2) of the database manager 126. The fist format may comprise a structured or fielded format compatible with a structured database wherein the database organization defines context of the data stored therein, allows for updates of individual fields without having modify other fields, etc. Generally, the data. store 124 holds long term data and other operational data for the system 100, including the content database 126.

The system 100 further includes a cache manager 110 coupled with the cache 118 and the content receiver 106, which may be implemented as a separate component or as one or more logic components, such as on an FPGA which may include a memory or reconfigurable component to store logic and processing component to execute the stored logic, or as third logic 110, e.g. computer program logic, stored in a memory 104, or other non-transitory computer readable medium, and executable by a processor 102, such as the processor 402 and memory 404 described below with respect to FIG. 4, to cause the processor 202 to, or otherwise be operative to determine whether to store the received content item in the cache 118 and, where it is determined to store the received content item in the cache 118, store, explicitly or implicitly, each of the received content item in a second format, different from the first format, in the cache 118 in association with data indicative of at least a subset of the subset of the plurality of keywords associated with the received content item, e.g. in the associated interest container. Thereby, as was described above, the received content item is stored in association with other stored previously received content items whose associated data is indicative of a subset of the plurality of keywords which at least partially overlaps the subset of the plurality of keywords associated with the received content item, e.g. in the associated interest container. The cache manager 110 and cache 118 may be implemented using the REDIS data structure server. The cache manager 110 may further be implemented as an asynchronous task. In one embodiment, content items are stored in the cache 118. Alternatively, content items 118 may be logically stored in the cache, e.g. they may be stored elsewhere in the memory 104 or data store 126 with reference identifiers/pointers thereto being stored in the cache 118. In one embodiment, the cache 118 may be sized to hold a container for every subset of keywords, e.g. every interest category, supported by the system 100. In addition, the content item stored in the cache 118 in the second format may be further stored in association with a reference identifier/pointer to the corresponding content items stored in the database 126 in the first format.

In one embodiment, upon initial startup of the system 100, an initial process may “seed” or otherwise pre-load the cache 118 with content items from the database 126 and converted from the first format to the second format. This seeding process may evaluate content items stored in the database 126 to determine a ranking value thereof, as described elsewhere herein, and preload the cache 118 with those content items whose ranking value exceeds a threshold value.

In one embodiment, the second format comprises JavaScript Object Notation (“JSON”). JavaScript Object Notation (JSON) is used, JSON is a lightweight text-based open standard for human-readable data interchange. It is used for serializing and transmitting structured data over a network connection. it may be used to transmit data between the system 100 and the device 116, providing a more efficient alternative to html. Although JSON is used in the exemplary embodiment, other formats, such as Extensible Markup Language (XML) can be used as a means of communication between the device layer and the application layer. In one embodiment, content items are converted to the second formation using response templates to convert from the first format to the second format. As shown in FIG. 2, the cache manager 110 may further include a response template processing component 212 which converts content items into the second format for storage in the cache 118.

In one embodiment, the second format is suitable for and used to transmit content items to the devices 116 whereas it is not suitable to use to store the content items in the database 126 because, for example, it is not compatible with the structure of the database 126. For example, JSON strings are easily transmitted as data packets over a network and easily rendered by the receiving device 116 to display the content items on the UI 146. However, JSON strings may not easily be parsed, managed or maintained as, for example, updating individual fields of data within a JSON string may require modifying the entire string. In contrast, a structured database may break up and store content item as multiple fields of data in one or more tables where the database structure imparts context to the data and facilitates field based queries and data modifications. As the disclosed system 100 utilizes two different formats for two purposes, it is necessary to convert content items from one format to the other depending on the purpose for which the content item is being used, e.g. stored in the database 126 or transmitted to the device 116. By caching content items in the second format, less processing resources are required when serving requests for those content items as they need not be converted to the second format before being transmitted to the device 116, resulting in improved response latencies and system 100 performance. By storing content items in the database 126 in the first format, system performance with respect to maintaining and identifying those content items is improved over performing such functions with respect to the second format.

In one embodiment, wherein the received content item is further sequentially and/or temporally associated with one or more previously received content items, e.g. related to a conversation or community, the received content item and the previously received content items being stored in the cache 118 and/or database 126 in association with each other, e.g. in a container, such that any determination of whether there are any previously received content items stored in the cache 118 and/or database 126 responsive to a request which identifies one of the received content or sequentially associated one or more previously received content items causes all, or a subset, of the received content and sequentially associated one or more previously received content items to be retrieved. In one embodiment, the set of associated one or more previously received content items are further divided into ordered, e.g. temporally, subsets, referred to as “pages”. In one embodiment, each subset may be sized to hold a sufficient number of content items to fill a defined display area of the user interface 146 of the device 116, e.g. one “screen full” and/or may include additional content items so as to create seamless/continuous viewing experience, in concert with transmission of the next subset, for the user when scrolling through the transmitted subset. Upon retrieval of a given content item, the subset or page of content items containing the retrieved content item may be transmitted to the user/device 116 first. As the user, via the user interface 146 of the device 116 interacts with the transmitted page, e.g. navigates to or views the last or next to last content item in the transmitted page, the user interface 146 may cause the device 116 to automatically request the next page from the system 100. Alternatively, or in addition thereto, the user interface 146 may provide a control, e.g. a “more” button, enabling the user to manually cause the device 116 to request the next, or a particular, subset/page. In this way, e.g. for large conversations, the content items thereof are sent in subsets on demand thereby saving bandwidth and processing resources of the both the system 100 and device 116. It will be appreciated that the cache may store a limited number of containers and/or a limited umber of conversations or communities within each container, e.g. 100 conversations.

In one embodiment, the cache manager 110 is further operative to determine whether the cache 118 has available capacity and store the received content item in the cache when the cache has available capacity. In one implementation the size of the cache 118 may 100 megabytes. In one embodiment the cache manager 110, via the cache maintenance processing module 214 (shown in FIG. 2) is further operative to evaluate, periodically and/or when the cache 118 is full or almost full, each or a subset of content items stored in the cache to compute a ranking value thereof, using the content ranking processor 216, and, wherein the computed ranking value does not exceed a threshold value, remove the content item or subset of content items from the cache.

In one embodiment, the cache manager 110 is further operative to determine to store the received content item in the cache 118 if previously received content items, whose associated data is indicative of a subset of the plurality of keywords which at least partially overlaps the subset of the plurality of keywords associated with the received content item, are stored in the cache 118. Accordingly, if a conversation or community is presently cached, new posts or updates to that conversation or community will also be cached.

In one embodiment, the cache manager 110 is further operative to compute, using the content ranking processing module 216, a ranking value of the received content item and store the received content item in the cache 118 if the computed ranking value exceeds a threshold. In one embodiment, the threshold is based on the computed ranking value of at least a subset of other previously received content items stored in the cache.

The system 100 further includes a request receiver 112 coupled with the network 138, which may be implemented as a separate component or as one or more logic components, such as on an FPGA which may include a memory or reconfigurable component to store logic and processing component to execute the stored logic, or as fourth logic 112, e.g. computer program logic, stored in a memory 104, or other non-transitory computer readable medium, and executable by a processor 102, such as the processor 402 and memory 404 described below with respect to FIG. 4, to cause the processor 202 to, or otherwise be operative to receive a request for content from a requester, e.g. at least one of the plurality of users/devices 116 via a network 138 coupled therewith.

As will be described in more detail below, requests received by the system 100 , which may be implemented as application program interface (API) calls, include update/refresh requests to receive the most recent new or modified content items, as well as search requests to receive specific content items matching a specified query. Requests may include the authentication token described above to validate the requesting user as being authorized to access the system. Update/refresh requests, which may also be referred to as implicit search requests, use the user's profile data, and the associated keyword/interest categories defined therein, to identify all content items in the system which match the user's interests. In one embodiment, update requests are automatically generated and transmitted to the system 100 by the application executing on the device 116 to “pull” updated content items when the device connects and is authenticated with the system 100, and may further be generated on an ad hoc basis by a user utilizing a refresh function provided by the 146 of their device 116. Alternatively, or in addition thereto, the system 100 may determine when content items of interest to a user have been updated, determine when users are currently connected, e.g. based on live sockets, and based thereon automatically transmit, i.e. “push”, updated content items to the user's device 116. Search requests, which may be referred to as explicit search requests, specify a query, will be described below, to cause the system 100 to return specific content items. Search requests may be manually generated by the user or may be automatically generated by the application executing on the device 116, such as via UI functions selectable by the user to retrieve particular content items, e.g. content items relating to a specific topic and/or time period.

In one embodiment, for at least the purpose of processing update requests, the system 100 further includes a user database, coupled with the processor, which may comprise the user content items 222 (shown in FIG. 2), as was described above, stored in the database 126 or may be a separate database stored in the data store 124 or memory 104, which includes a plurality of data records, each associated with one user of the plurality of users, each data record further comprising data indicative of a subset of the plurality of keywords selected, e.g. interest categories selected by the user as described above, from the plurality of keyword sets, wherein the request for content comprises an update request, the search manager 114 is further operative to identify the user from which the request for content was received, retrieve the data record from the user database associated with the identified user and determine the identified keywords to use to locate the content items of interest based on the subset of the plurality of keywords of the retrieved data record. In one embodiment, request may be temporally limited, e.g. the time of receipt of the request for content as compared to a previously received request for content received from the same user is determined and only content items that were not previously sent to the user are sent responsive to the request. Alternatively, the device 116, or application executing thereon, may communicate an indication of the state of any content items stored locally in the device 116 wherein the system 100 utilizes the provided state information to avoid sending redundant or irrelevant/outdated content items to the user.

Alternatively, it will be appreciated that the user's interest categories/keywords may be stored in the device 116 and transmitted to the system 100 as part of the request.

The system 100 further includes a search manager 114 coupled with the request receiver 112, database manager 108 and cache manager 110, which may be implemented as a separate component or as one or more logic components, such as on an FPGA which may include a memory or reconfigurable component to store logic and processing component to execute the stored logic, or as fifth logic 114, e.g. computer program logic, stored in a memory 104, or other non-transitory computer readable medium, and executable by a processor 102, such as the processor 402 and memory 404 described below with respect to FIG. 4, to cause the processor 202 to, or otherwise be operative to identify, automatically based on the received request, one or more keywords selected from the plurality of keyword sets. This process may be referred to as Interest Processing and performed by an Interest Processing module 202 (shown in FIG. 2) of the search manager 114. They identified keywords may be automatically identified from the user profile associated with the user who submitted the request, as described above, and/or may have been included with the request, e.g. in an explicit query.

The search manager 114, in one embodiment, includes an input processing module 228 (shown in FIG. 2) Which processes the search request to determine the search parameters included therein and values/value ranges thereof and determines the proper search method to invoke within the search processing module 202 (shown in FIG. 2).

The search processing module 202 includes/implements a set of methods/processes which search the database 126 and the cache 118, as will be described, for query matches based on the search parameters specified in the request. As will be described, the search processing module 202 may communicate with the response quota processing module 206 to ensure a minimum required result set is met and expands it's search scope using the scope processing module 208 when the minimum result set is not met. These three modules may work in sequence until the minimum result set is reached. Once the quota has been met, the search processing module 202 may communicate with the ad processing module 210 to determine a set of advertisement messages based on the user's profile data and/or the search request. The ad processing module 210 maybe coupled with a ad database 144 stored in the data store or an ad cache (not shown) stored in the memory 104 to identify general and/or suitable/targeted, i.e. based oil the user's selected interest categories and/or one or more search parameters of their search request, advertisement messages previously received from the external ad networks 114. Where no suitable previously received advertisement messages are stored, the ad processing module 210 may communicate with one or more external ad networks 134 via the network 138 to obtain suitable advertisement messages. Obtained advertisement messages may be stored in ad database 144/ad cache for subsequent retrieval. The advertisement messages may comprise advertising content or references/links (meta-information) thereto and may be stored in the ad database 144/ad cache in association with selected keywords/interest categories to facilitate later retrieval. Advertisement messages retrieved from the ad database 144/ad cache and/or from the ad networks 134 may then be inserted/injected into the result set of content items to be provided to the user responsive to the user's search query.

The search manager 114 being further operative to determine, based the user profile, in the case of a an update request or the search parameters, the case of a search request, e.g. based on at least a subset of the identified keywords, whether there are any previously received content items stored in the cache 118 in association with the subset of the identified keywords and, if there are any previously received content items stored in the cache 118 in association with the subset of the identified keywords, cause transmission of all, e.g. the entire contents of the associated interest container, or at least a subset, e.g. time, previously-seen, or client-state limited, of those determined previously received content items from the cache 118 to the requester, i.e. in the second format, e.g. JSON. In one embodiment, if any content items are found in the cache 118, no further lookups are made to the database 126. Alternatively, once content items are found in the cache 118, the search manager also looks in the database 126, either before or after transmitting the content items from the cache 118 to the device 116.

Where there are no previously received content items stored in the cache 118 in association with the subset of the identified keywords, or in embodiments where both the cache 118 and database 126 are searched, the search manager 114 is further operative to determine, based on at least the subset of the identified keywords, whether there are any previously received content items stored in the database 126 in association with the subset of the identified keywords and if there are any previously received content items stored in the database 126 in association with the subset of the identified keywords, retrieve all, e.g. the entire contents of the associated container, or at least a subset e.g. time, previously-seen, or client-state limited, of those determined previously received content items from the database 126, convert the retrieved content items from the first format, e.g. structured/fielded format to the second format, e.g. JSON, store the converted content items in the cache 118 in association with data indicative of at least a subset of the subset of the plurality of keywords associated with the retrieved content items, i.e. in the same container, and cause transmission of the converted retrieved content items to the requester/device 116, i.e., in the second format, e.g. JSON. Storing the content items in the cache 118 expedites processing of that content item for later requests, e.g. assuming that a search request which results in one or more content items is indicative of its likelihood of those content items to be requested again.

The results of an update or search request, i.e. the identified previously received content items, may include user content items associated with people with one or more interests in common as well as conversation and community content items associated wit one or more common interests. It will be appreciated that other data may also be sent back to the client 116 responsive to the receipt of the request including notification messages, direct messages or other system messages as well as updates to followed user content items, participating conversations or subscribed communications where the user's selected interest categories or query do not match but the user is still following, participating or subscribing thereto. Other data sent back to the device 116 may include content items identified as trending within the system, such as based on the frequency and/or volume of user activities occurring with respect to the content item or the interest categories associated therewith, or trending external to the system 100, such as on the Internet, e.g. current events, etc. The content generator 134 may further include a trending processing module 218 (shown in FIG. 2) coupled with external content sources 132 via the network 138, such as news or entertainment news services or web sites, which determines and obtains relevant content and converts that content to content items, such as by using the scraping module 220. The trending content items, which may be referred to as stories, may then be stored in the cache 118 in a trending store 122 in the second format for provision to users along with search results.

FIG. 5 depicts exemplary operation of the system 100 when responding to an update request. As shown in FIG. 5, the user/client 116 sends an authenticated update request, e.g. a request current content matches, generated upon connection of the device 116 to the system or based on selection of a. refresh/update operation by the user or initiated by the device 116 (001). Upon receipt of the update request, the system 100 derives the identity of the user from the request, obtains the user's profile from the database 126 (or from the request itself) (002) and determines the user's selected interest categories (003). The interest/search processing module 202 of the search manager 114 accesses and searches the cache 118 based on the user's selected interest categories. Any results of the search are returned to the search manager 114 in the second format, e.g. JSON (004). If no results are retrieved from the cache 118, the search manager queries the database 126 and converts any results received therefrom from the first format to the second format. The system 100 then orders and ranks the received content based on ranking principles described above and then transmits the content items, or one or subsets/pages thereof, as was described above, to the device 116 (006) which received and displays the content items, or subset thereof, to the user (007).

FIG. 6 depicts an example of operation of the system 100 when responding to a search request. In particular, as shown in FIG. 6, a user makes a search request which contains search inputs (001). The search manager 114 of the system 100 receives search parameters and input processing module 228 of the search manager 114 routes the query to the search processing module 202 (002). The search processing module 202 searches the interest containers 222, 224, 226 of the cache 118 for any matching pieces of content (003). The search processing module 202 then sends the result set from the cache to the response quota processing module 206 to determine whether the minimum result set has been met. If the minimum size has not been met, then the search processing module 202 does a database search within the database 126 to find any content items that match the search query (004). The response quota processing 206 again checks whether the result set meets the minimum requirements. At this point if the result set still does not meet the minimum requirements, then the scope processing module 208 is used to expand the scope of the search parameters, as was described above, and the search process returns to step 003. If multiple passes, as defined by the system 100, e.g. 3, through the scope processing module 208 still do not return the minimum required set then the existing result set is assumed to be best fit (005). The best fit result set has been found at this point. The ad processing module 210 may then be called to provide one or more applicable advertisement messages based on the user's profile and/or search query. The ad database 144 is checked first and if no ads are found locally then an ad request is made to an external add network 134. The returned advertisement messages are inserted/injected into the result set (006). The system 100 formats the any content items that are not in the second format, e.g. JSON, into the second format and sends the response, or subset/page thereof, as described above, back to the client 116 (007). The client 116 receives and displays result set (008).

In one embodiment, as shown in FIGS. 7-9 and described in more detail below with respect to FIGS. 10-11, wherein the received content item 1308 further includes, or is associated with, data indicative of a geographic location, e.g. latitude/longitude, Cartesian coordinates, etc., related to the content item, such as the location from which the content item originated or other geo-tag, the data indicative of a geographic location may be provided back to the device 116 along with the associated content items so as to enable display of an indication 1302 of the indicated geographic location of the content items 1308 by the receiving device 116 on the user interface 146 geographically, such as via a map or globe display, relative to a display of an indication 1302 of the indicated geographic location of another received content item 1308, as will be described in more detail below. in one embodiment, this display make take form of a map or globe 1300 presentation which may or may not be user-manipulatable, e.g. movable via user interaction with the user interface or otherwise, so as to show different geographic regions on the display, zoomable to show more or less detail on the display, etc. Furthermore, the receiving device's location may also be represented on the display in relation to the displayed content items 1302 to demonstrate the geo-physical relationship between the user thereof and the content items 1308 transmitted to them. In one embodiment, graphical representations 1304 of relationships between particular displayed content items 1308 may be implemented such as arcs, curves, lines or other connectors, drawn or graphically depicted between, i.e. connecting, the geographic location indicators 1302, and/or displaying related content items 1308 or geographic indicators 1302 in a similar particular color or other depiction or otherwise similarly highlighting, moving, wiggling, magnifying, etc. the depiction of the related content items. it wil l be appreciated that geo-physical relationships may further the discovery of content of interest as users may be interested in any content originating from a particular location, such as their own location, or somehow related thereto. It will be appreciated that the search/update request processes described above may further factor in the geographic location of the requesting user/device 116 as compared to the geographic locations of the content items when determining which content items to transmit to the device 116. In one embodiment, the client device 116 receives the result set from the system 100 and begins sorting the locations of the received content items into groups based on their geo-graphical location. The grouping algorithm has a set of grids that map onto a sphere and for every point that falls into a grid, that point 1306 is added to a “group point” that appears at the center of that grid. The geographic indicators 1302 may comprise visual “TicPoints” 1306 which may be created at the center of every grid which had a point found within it. The TicPoint 1306 may display the number of points that were grouped within that grid, or if only one point was found, that point's image is shown. Alternatively, or in addition thereto, the user interface 146 of the device 116 may permit the user to zoom in and out of the geographical display 1300 and as the user zooms in and out, at specific zoom levels, the points on the globe are regrouped/coalesced to show more or less singular points. This allows for a large data set to be displayed without appearing cluttered on the screen. Further, connections between associated points on the globe may be visualized by display of arcs of light between the associated points to depict associations between these points and their meta data and may be determined by common interactions between users including posting into the same conversations, common and mutual follows, and post locations.

FIG. 3 depicts a flow chart showing operation of the system 100 of FIGS. 1 and 2. In particular FIG. 3 shows a method of distributing a content item, provided by a source to a content distribution system 100, to a subset of a plurality of users via a network 138 coupled therewith, the content distribution system comprising a processor 102, a memory 104 coupled with the processor and a data store 124 coupled with the memory 104 and the processor 102, the memory 104 comprising a cache 118 and the data store 124 comprising a database 126.

The operation of the system 200 includes: receiving, by the processor, the content item from the source, the content item being associated with data indicative of a subset of a plurality of keywords selected from a plurality of keyword sets, each keyword set comprising a hierarchical sequence of keywords, wherein for each keyword set a first keyword of the sequence of keywords defines a context, different from a context defined by a first keyword of a different keyword set, and each subsequent keyword of the sequence of the keyword set defines a narrowing of the context over the previous keyword of the sequence of the keyword set [Block 302]; storing, by the processor, each of the received content item in a first format in the database in association with data indicative of at least a subset of the subset of the plurality of keywords associated with the received content item [Block 304]; determining, by the processor, whether to store the received content item in the cache and, where it is determined to store the received content item in the cache, storing, by the processor, each of the received content item in a second format, different from the first format, in the cache in association with data indicative of at least a subset of the subset of the plurality of keywords associated with the received content item [Block 306]; receiving, by the processor, a request for content from a requestor via the network [Block 308]; identifying, by the processor, based on the received request, one or more keywords selected from the plurality of keyword sets [Block 310]; determining, by the processor based on at least a subset of the identified keywords, whether there are any previously received content items stored in the cache in association with the subset of the identified keywords and, if there are any previously received content items stored in the cache in association with the subset of the identified keywords [Block 302], causing, by the processor, the transmission of at least a subset of those determined previously received content items from the cache to the requestor via the network [Block 314]; and where there are no previously received content items stored in the cache in association with the subset of the identified keywords, determining, by the processor based on at least the subset of the identified keywords, whether there are any previously received content items stored in the database in association with the subset of the identified keywords [Block 316] and if there are any previously received content items stored in the database in association with the subset of the identified keywords, retrieving, by the processor, at least a subset of those determined previously received content items from the database [Block 318], converting, by the processor, the retrieved content items from the first format to the second format [Block :320], storing, by the processor, the converted content items in the cache in association with data indicative of at least a subset of the subset of the plurality of keywords associated with the retrieved content items, and causing, by the processor, transmission of the converted retrieved content items to the requester via the network [Block 322].

In one embodiment, the source comprises a device 116 operated by a user of the plurality of users. In one embodiment, the second format comprises JavaScript Object Notation (“JSON”).

In one embodiment, wherein the received content item is further sequentially associated with one or more previously received content items, the received content item and the previously received content items may be stored in the cache 118 and/or database 126 in association with each other such that any determination of whether there are any previously received content items stored in the cache 118 and/or database 126 responsive to a request which identifies one of the received content or sequentially associated one or more previously received content items causes all, or at least a subset, of the received content and sequentially associated one or more previously received content items to be retrieved. In one embodiment, the set of associated one or more previously received content items are further divided into ordered, e.g. temporally, subsets, referred to as “pages”. In one embodiment, each subset may be sized to hold a sufficient number of content items to fill a defined display area of the user interface 146 of the device 116, e.g. one “screen full” and/or may include additional content items so as to create seamless/continuous viewing experience, in concert with transmission of the next subset, for the user when scrolling through the transmitted subset. Upon retrieval of a given content item, the subset or page of content items containing the retrieved content item may be transmitted to the user/device 116 first. As the user, via the user interface 146 of the device 116 interacts with the transmitted page, e.g. navigates to or views the last or next to last content item in the transmitted page, the user interface 146 may cause the device 116 to automatically request the next page from the system 100. Alternatively, or in addition thereto, the user interface 146 may provide a control, e.g. a “more” button, enabling the user to manually cause the device 116 to request the next, or a particular, subset/page. In this way, e.g. for large conversations, the content items thereof are sent in subsets on demand thereby saving bandwidth and processing resources of the both the system 100 and device 116.

In one embodiment, the determining of whether to store the received content item in the cache may further include determining whether the cache 118 has available capacity and storing the received content item in the cache 118 when the cache 118 has available capacity. In one embodiment, the determining of whether to store the received content item in the cache may further include determining to store the received content item in the cache 118 if previously received content items, whose associated data is indicative of a subset of the plurality of keywords which at least partially overlaps the subset of the plurality of keywords associated with the received content item, are stored in the cache 118. In one embodiment, the determining of whether to store the received content item in the cache may further include computing a ranking value of the received content item and store the received content item in the cache 118 if the computed ranking value exceeds a threshold. In one embodiment, the threshold may be based on the computed ranking value of at least a subset of other previously received content items stored in the cache 118.

In one embodiment, the content distribution system may further include a category database 148 operative to store the plurality of keyword sets wherein each keyword within each keyword set is identified by a unique identifier, and further wherein the data indicative of a subset of the plurality of keywords comprises the unique identifiers of the respective keywords as stored in the category database 148.

In one embodiment, the system 100 may further include a user database 222, coupled with the processor 102, which includes a plurality of data records, each associated with one user of the plurality of users, each data record further comprising data indicative of a subset of the plurality of keywords selected from the plurality of keyword sets, wherein the request for content comprises an update request, the identifying further comprising identifying the user from which the request for content was received, retrieving, by the processor, the data record from the user database associated with the identified user and determining the identified keywords based on the subset of the plurality of keywords of the retrieved data record.

In one embodiment, the request for content may specify a content scope, the identifying further comprising determining the identified keywords based on the content scope. In one embodiment, the operation of the system 100 may further include establishing a minimum number of content items to transmit responsive to the request for content, and wherein if the number of determined previously received content items in the cache 118 or database 126 does not exceed the minimum number of content items to transmit, modifying, by the processor 102, the specified content scope so as to increase the number of determined previously received content items in the cache 118 or database 126.

In one embodiment, the operation of the system 100 further includes: evaluating, by the processor 102, a subset of content items stored in the cache 118 to compute a ranking value thereof; and wherein the computed ranking value does not exceed a threshold value, removing the subset of content items from the cache 118. In one embodiment, this ranking is computed periodically. Alternatively, or in addition thereto, it may be computed when the content item is stored in the cache 118 and may be recomputed when the content item, having been previously removed from the cache 118, is retrieved from the content database 126 and again stored in the cache 118.

In one embodiment, the received content item may further include data indicative of a geographic location related to the content item, wherein the data indicative of a geographic location is operative to enable display of an indication of the indicated geographic location of the content item by the receiving requester geographically relative to a display of an indication of the indicated geographic location of another received content item.

In one embodiment, the received content item includes content characterized by a first language and further wherein the received request is associated with a second language, the operation of the system 100 may further include determining whether the first language of content items to be transmitted is the same as the second language and if not, translating, by the processor 102, the content of each of the content items from the first language to the second language prior to transmission, In one embodiment, the system 100 may further include a translation cache 128 coupled with the processor 102, the operation of the system 100 further including determining, for each content item to be transmitted, whether a translation of the content thereof in the second language is stored in the translation cache 128 and if so, retrieving the translation and if the translation is not stored in the translation cache 128, translating the content from the first language to the second language and storing the translation in the translation cache 128.

The system 100 or device 116, or application executing thereon, described above may, may operate or be implemented in accordance with the embodiments described in Appendix A, included herewith and incorporated by reference herein, including the operation of the user interface 146 with respect to the geographical display of the locations of the content items and other functional aspects.

FIG. 10 depicts a block diagram of a system which implements the geographic displays of FIGS. 7-9 according to on embodiment. In particular, FIG. 10 depicts a block diagram of an example system 1000 for generating a representation, e.g. a two dimensional representation, of geographic relationships, e.g. within a three dimensional region, such as a globe, among a plurality of data items, e.g. content items described above. The system 1000 may be implemented in the client device 116, described above, coupled , or otherwise used in conjunction with the system 100, described in detail above with respect to FIG. 1, such as via the network 138. It will be appreciated that the system 1000 could be implemented in other client devices and/or used in conjunction with other types of content distribution systems, e.g. other social networking services, which provide the requisite data items as described herein.

The example system 1000 as well as the disclosed embodiments used in conjunction therewith are preferably implemented with computer devices and computer networks, such as those described with respect FIG. 4 and improved as described herein, that allow users, e.g. members or participants, to interact with the social networking service, e.g. submit content items to the social networking service and receive content items submitted by others. It will be appreciated that the plurality of entities utilizing the disclosed embodiments may be referred to by other nomenclature reflecting the role that the particular entity is performing with respect to the disclosed embodiments and that a given entity may perform more than one role depending upon the implementation and the nature of the particular transaction being undertaken, as well as the entity's contractual and/or legal relationship with another participant and/or the system 1000.

In particular, FIG. 10 depicts a block diagram of a system 1000, which may also be referred to as an architecture, for generating a representation 1300, e.g. a two dimensional representation, of geographic relationships, e.g. within a three dimensional region, such as a globe, among a plurality of data items 1302, 1306, e.g. content items described above, the system 1000 comprising a processor, 1002, memory 1004 coupled with the processor 1002 and a data store 1010 coupled with the processor 1002 and/or memory 1004, the data store 1010 operative to store data items 1302, 1306, e.g. content items, received from the system 100 as described above, e.g. a result set responsive to search or update requests by the client device 116 to the system 100. In one embodiment, the network 138, processor 1002, memory 1004 and data store 101.0 may be implemented by one or more of the network 420, processor 402, the memory 404 and drive unit 406 described below with respect to FIG. 4. The data store 124 may be s separate from or, alternatively, stored within the memory 1004. It will appreciated that the data store 1010 could comprise a memory 404 or memory 404. in combination with a drive unit 406 and may be logically and/or physically combined with the memory 1004. The client device 116 may store other data as well in the memory 1004 or data store 1010.

The rendering processor 1008 being further operative to, for each of the one or more related data items 1306 whose geographic location is located within the portion of the three dimensional representation of the geographic region depicted by the computed two dimensional representation 1300, compute a location thereof within the two dimensional representation 1300 and cause a representation 1306 thereof to be included within or otherwise superimposed over the presentation on the display 146 of the two dimensional representation 1300, cause, for each of the one or more related data items, a visual depiction 1304 of a connection between, or otherwise extending to/from, the representation of the related data item 1306 and the representation of the origin data item 1302 to be included within or otherwise superimposed over the presentation on the display 146 of the two dimensional representation 1300, wherein for each of the one or more related data items 1306 displayed within the two dimensional representation 1300, the visual depiction 1304 extends from the representation of the origin data item 1302 to the representation of the related data item 1306 and wherein for each of the one or more related data items 1306 not displayed within the two dimensional representation 1300, the visual depiction 1304 extends from the origin data item 1302 to or towards a boundary of the portion of the three dimensional representation of the geographic region depicted by the two dimensional representation 1300 in a geographic direction, as depicted in the two dimensional representation 1300, of the geographic location of the related data item. In one embodiment, the visual depiction 1304 has the appearance of extending over the “horizon” from the origin data item 1302 to the unseen related data item 1306. Alternatively, in one embodiment, for each of the one or more related data items 1306 not displayed within the two dimensional representation 1300, an indicator of the non-displayed related data item 1306 is displayed at the boundary of the portion of the three dimensional representation of the geographic region depicted by the two dimensional representation 1300, e.g. on the “horizon”, in a geographic direction, as depicted in the two dimensional representation, of the actual geographic location of the related data item. The indicator of the non-displayed item may comprise an arrow other indicator to indicate to the user that the related data item's geographic location is hidden or that, otherwise, the two dimensional representation must be altered in order to see it, e.g. the globe must be rotated or spun to bring it into view. In this embodiment, the visual depiction 1304 may be shown as extending from the origin data item 1302 to the indicator at the boundary/horizon.

In one embodiment, the origin data item 1302 may include data indicative of a portion of a discussion, as described above as part of a conversation, message or post, the included geographic location being associated therewith, e.g. the location is related to the topic of discussion or the location of the user who provided the portion of the discussion, and wherein the one or more related data items 1306 may further comprise data indicative of other portions of the discussion, or of other users participating (who contributed portions) to that discussion.

In one embodiment, the origin data item may include data indicative of a participant of a social network, the included geographic location being associated therewith, e.g. provided in a user profile, or otherwise determined by the system 100 or system 1000, e.g. based on location data provided by the participant's device (GPS, IP address) or by the user, the one or more related data items 1306 each comprising data indicative of another user related thereto, such a connection, a followed user or a user the participant is following.

In one embodiment, the origin data item 1302 may include data indicative of a topic of a discussion, such as a community as descried above, the included geographic location being associated therewith, e.g. a geographic context of the topic, wherein the one or more related data items 1306 may each include data indicative of a user subscribed to the topic of discussion, e.g. participating in, or otherwise subscribed to, the community.

In one embodiment, the rendering processor 1008 may be further operative, e.g. automatically, to repeat, i.e. refresh, the computation of the two dimensional representation 1300, causation of the determined two dimensional representation 1300 to be interactively presented on the display 146, determination of the one or more related data items 1306 related to the origin data item 1302, computation of the location of each of the one or more related data items 1306 on. the three dimensional representation of the geographic region, computation of the location thereof within the two dimensional representation 1300 and causation of a representation thereof to be included within or otherwise superimposed over the presentation on the display 146 of the two dimensional representation 1300, and causation, for each of the one or more related data items 1306, a visual depiction 1304 of a connection between, i.e. extending to/from, the representation of the related data item 1306 and the representation of the origin data item 1302 to be included within or otherwise superimposed over the presentation on the display 146 of the two dimensional representation 1300. In one embodiment, the repetition/refresh may occur automatically at a rate which creates a perception by the user of the device 116 of seamless movement of the presentations and connections as data items are moved into and out of view, etc., such as 30 frames per second.

In particular, in one embodiment the selection receiver 1006 may be further operative to detect user interaction with the two dimensional representation 1300, such as via the user interface 146, to alter the selection of the origin data item 1302, e.g. by selecting a different data item, e.g. one of the related data items 1306, to be the origin date item 1302, the rendering processor 1008 being further operative to repeat/refresh based thereon.

In particular, in one embodiment the selection receiver 1006 may be further operative to detect user interaction with the two dimensional representation 1300, such as via the user interface 146, to alter the portion of the three dimensional representation depicted thereby, the rendering processor being further operative to repeat/refresh based thereon. For example, the user may change which portion of the geographic region is displayed by, for example, moving, spinning, rotating, etc., the depicted map/globe or otherwise zooming in closer to show a more detai led but smaller portion of the region or out to show less detail but a larger portion of the region. Each such change would change which geographic locations are depicted within the two dimensional representation 1300 and thereby, which of the related data items 1306 may be depicted therein.

In particular, in one embodiment the selection receiver 1006 may be further operative to detect a change to the one or more related data items 1306, e.g. added or removed, the rendering processor 1008 being further operative to repeat based thereon. For example, the selection receiver 1006 may detect when new related content items are posted or removed, users are added or removed, communities are created or removed, user follow or unfollow another user, uses subscribe or unsubscribe to a community, etc. These changes may be detected responsive to the receipt of content items from the system 100, e.g. responsive to a search or update request as described above.

In one embodiment, the causing, for each of the one or more related data items 1306, a visual depiction 1304 of a connection between the representation of the related data item 1306 and the representation of the origin data item 1302 to be included within or otherwise superimposed over the presentation on the display 146 of the two dimensional representation 1300 further comprises computing, by the processor 1002, one or more parameters of a graphical indicator, such as an arc or Bezier curve, of a connection between, or otherwise projecting from the representation of the origin data item 1302 and each of representations of the one or more related data items 1306.

For example, a piece of content, e.g. an origin data item 1302, in the system 100 can be related or connected to many other pieces of content, e.g. related data items 1306. These connections may, as described herein, be shown via an “arc of light” 1304 in the two dimensional representation 1300, e.g. the TicTalking 3D GeoGlobe. In one embodiment the connection 1304 are drawn as follows:

First the server returns a data point, e.g an origin data point 1302, that the client has requested. This data point contains a latitude longitude (“lat lon”) position as well as the latitude longitude positions of all related content 1306. For each lat lon of related content we use a method which converts the lat lon into a Cartesian (x,y,z) point on the GeoGlobe. This calculated position as well as the calculated Cartesian position of the original data point (using the same method) are used as the starting and ending points in a Bezier curve formula. With the Bezier formula the two middle points of the curve will need to be calculated. In order for the Bezier curve to align with the curvature of the globe sphere, a series of vector transformations are used to obtain these middle points.

A Bezier curve is a parametric curve frequently used in computer graphics and related fields. Generalizations of Bezier curves to higher dimensions are called Bezier surfaces, of which the Bezier triangle is a special case.

In vector graphics, Bezier curves are used to model smooth curves that can be scaled indefinitely. “Paths”, as they are commonly referred to in image manipulation programs, are combinations of linked Bezier curves. Paths are not bound by the limits of rasterized images and are intuitive to modify.

First the vector direction between the start and end point is obtained, as well as the distance between them. Two reference points are then calculated along the line between the start and end points. This is done by adding the starting position to the product of the calculated direction, distance, and a line offset value. (in the supplied method the offset values are 10 and 90 percent which best suited the look of the app). Next the rotation of the Bezier curve needs to be calculated to align it with the curvature of the earth. This is done by taking the midpoint between the start and end points and calculating the relative vector direction to the center of the globe sphere (which in this case is 0,0,0 but it could be located elsewhere) The previously calculated reference points are then added to the products of the rotation offset direction and a distance component which gives you the required middle points for your rotation offset Bezier curve.

Aside: This method does not work if the two points are oriented directly through the center of the sphere. This is because the rotation offset direction in this case would be zero. Accordingly, in one embodiment, a small random perpendicular angle will be substituted for the direction vector.

public static Vector3 CalculateBezier(float t, Vector3 start, Vector3 end) {  Vector3 P1 = start;  Vector3 P4 = end;  Vector3 dir = (P4 - P1).normalized;  float dist = Vector3.Distance( P4, P1 )  Vector3 p2 = P1 + dir * dist * 0.10f;  Vector3 p3 = P1 + dir * dist * 0.90f;  Vector3 midPoint = (end + start) / 2;  Vector3 direction = (midPoint - Vector3.zero).normalized;  Vector3 P2 = p2 + direction * (dist*dist/350f);  Vector3 P3 = p3 + direction * (dist*dist/350f);  t = Mathf.Clamp(t,0f,1f);  Vector3 A1 = P1 + (P2-P1) * t;  Vector3 A2 = P2 + (P3-P2) * t;  Vector3 A3 = P3 + (P4-P3) * t;  Vector3 B1 = A1 + (A2-A1) * t;  Vector3 B2 = A2 + (A3-A2) * t;  return B1 + (B2-B1) * t; }

The Bezier curve is thereby calculated between two points which can now be used to spawn a graphical arc. Take 1 divided the number of line segments in the arc to calculate t values to plug into the Bezier formula. Then iterate through these t values and position each point in the arc to the output of the Bezier formula at that t value.

In one embodiment wherein the geographic region, e.g. the world, is characterized by a surface having a shape, e.g. spherical, the two dimensional representation 1300 depicting the shape of the geographic region and wherein the visual depictions 1304 are generated so as to visually conform to the depicted shape, e.g. as arcs.

In one embodiment, the visual indicators 1304 are characterized by a dynamic appearance causing the perception of movement, e.g. flow, thereof from the representation of the origin data item 1302 to the representation of the related data item 1306 connected thereby. In one embodiment, this may only be shown upon selection of the arc 1304 or the related data item 1306 connected to the origin data item 1302.

In one embodiment, the visual indicators 1304 may be not shown on the two dimensional representation 1300 either by default and/or via an interaction by the user, such as via a setting, to add or remove them from being displayed.

In one embodiment, the causing of the determined two dimensional representation 1300 to be interactively presented on a display 146 coupled with the processor 1002 and further causing a representation of the origin data item 1302 to be included within or otherwise superimposed over the presentation on the display 146 of the two dimensional representation 1300 at the computed location, and, for each of the one or more related data items 1306 whose geographic location is located within the portion of the three dimensional representation of the geographic region depicted by the computed two dimensional representation 1300, the computing of the location thereof within the two dimensional representation 1300 and causing a representation thereof to be included within or otherwise superimposed over the presentation of the two dimensional representation 1300, further comprise combining, by the processor 1002, a first view comprising the three dimensional representation of the geographic region with a second view comprising the two dimensional representation 1300, e.g. using two cameras.

In 3D video games, a virtual camera system aims at controlling a camera or a set of cameras to display a view of a 3D virtual world. Camera systems are used in videogames where their purpose is to show the action at the best possible angle; more generally, they are used in 3D virtual worlds when a third person view is required.

For example, there may be two cameras in an application implemented in accordance with the disclosed embodiments, such as the TicTalking app produced by TicTalking Inc. and implemented using the Unity cross-platform game engine developed by Unity Technologies, located in San Francisco, Calif., Which are used to position and view points on the two dimensional representation 1300, e.g. the TicTalking GeoGlobe. Each frame update combines the views of these two cameras together to form the final output frame that the user sees on the display 146. The first camera (Camera 1) renders the globe sphere and reference point markers, while the second (Camera 2) renders the 2D graphical points. The method of updating the position of the 2D graphical points on top of a 3D globe is what makes this procedure unique.

Assuming that the marker points have already been positioned on the globe via a method which converts a latitude longitude into a Cartesian x,y,z position:

For each TicPaint needed to be rendered on the globe, the following takes place every frame update.

Take the Vector3 position (x,y,z) of the marker point and convert it's position into a 2D pixel position via a WorkfToViewPoint Method relative to Camera 1. This method returns a Vector2 position (x,y) which represents the current pixel position in Camera 1 that the point marker is being rendered. We then take this pixel position and use it as the input in a ViewPortoWorldPoint method on Camera 2 which returns a Vector3 position relative to Camera 2. This gives us the world space rendering position of our graphical TicPoint in Camera 2 for that frame. We then spawn the graphical portion of the TicPoint and set it's Cartesian position to the calculated position for the duration of that frame.
